Mercurial appears to resolve cwd-relative path first, so "glob:*.c" could be
parsed as "**/*.c" if cwd was literally "**". It wouldn't practically matter,
but isn't correct. Instead, jj's parser first splits glob into literal part
and pattern. That's mainly because we want to parse the user input texts into
type-safe objects, and (RepoPathBuf, glob::Pattern) pairs are the simplest
ones. The current parser can't handle patterns like "foo/*/.." (= "foo" ?),
and errors out. I believe this restriction is acceptable.
Unlike literal paths, the 'glob:' pattern anchors to the whole file path. I
don't think "prefix"-matching glob is useful, and making it the default would
be rather confusing.
It's cheap to look up commits again from the cache in `Store` but it
can be expensive to look up commits we didn't end up needing. This
will make it easier to refactor further and be able to cheaply set
preliminary parents for a rewritten commits and then let the caller
update them.
I'm going to add a helper struct to help with rewriting commits. I
want to make that struct own the old commit and the new parents to
simplify lifetimes. This patch prepares for that by passing the
commits by value to `rebase_commit()`.
This is the last non-debug command that doesn't support file patterns. It
wouldn't make much sense to "cat" multiple files (despite the command name),
but doing that should be harmless.
Prepares for migrating to the matcher API. "Path exists but is not a file"
error is turned into a warning because the loop shouldn't terminate there.
"No such path" error message is also updated for consistency.
if `--use-destination-message/-u` is passed to `jj squash`, the resulting
revision will use the description of the destination revision and the
description(s) of the source revision(s) will be discarded.
If we ever implement some sort of ABI for dynamic extension loading, we'll need these underlying APIs to support multiple extensions, so we might as well do that first.
This command checks not only whether Watchman works, but also whether
it's enabled in the config. Also, the output is easier to understand
than that of the other `jj debug watchman` commands.
It would be nice if `jj debug watchman` called `jj debug watchman
status`, but it's not trivial in `clap` to have a default subcommand.
Ilya reported this in https://github.com/martinvonz/jj/issues/3483.
The bug was introduced in 976320726d.
Before this fix, `jj split` dropped any parents what weren't involved in the
split when it rebased the children of the commit being split. This meant that
any children which were merge commits lost their other parents unintentionally.
Fixes#3483
Maybe we can optimize it to check paths during diffing, but I think it's okay
to add extra lookup cost at the end. The size of the path arguments is usually
small.
Closes#505
Path parsing will be migrated to parse_union_filesets(), but I haven't decided
how we'll go forward:
a. migrate everything to fileset
b. require flag like "-e FILESET" (note -p conflicts with log -p)
c. require flag like "-e FILESET" and deprecate positional PATHs #2554
d. require prefix like "set:FILESET" (not consistent with -r REVSET)
I'm currently dogfooding (a). It works for me, but I don't use exotic file
names that would require quoting in zsh.
#3239
Before this commit `jj prev` fails if the current working copy commit is a
merge commit. After this commit it will prompt the user to choose the ancestor
they want to select.
#2126
This will hopefully make it clear that `jj prev` does not
move by [OFFSET] relative to `@`, which is a misconception
that I had and I think others may also have.
I am suggesting this change as a result of the vigorous discussion in
these two issues:
- https://github.com/martinvonz/jj/issues/3426
- https://github.com/martinvonz/jj/pull/3445
We should make similar changes to `jj next` as well since
it follows similar rules.
This is basically the same as string kind:pattern syntax in CLI. This will
hopefully be superseded by filesets, but I'm not sure if that will work out.
A file name is more likely to contain whitespaces, which will have to be
quoted as '"Documents and Settings"'.
Parallelize revisions by making them siblings
Running `jj parallelize 1::2` will transform the history like this:
```text
3
| 3
2 / \
| -> 1 2
1 \ /
| 0
0
```
Each of the target revisions is rebased onto the parents of the root(s) of
the target revset (not to be confused with the repo root). The children of
the head(s) of the target revset are rebased onto the target revisions.
The target revset is the union of the REVISIONS arguments.
The target revset being parallelized must satisfy several conditions,
otherwise the command will fail.
1. The heads of the target revset must not have different children.
2. The roots of the target revset must not have different parents.
3. The parents of all target revisions except the roots must also be
parallelized. This means that the target revisions must be connected.
Offset is a more descriptive noun for this argument. This commit also tweaks
the help message for the argument.
This isn't an option/flag, so this change should be transparent to users.
This function doesn't actually need commits, it only needs their IDs. In some
contexts we may only have commit IDs, so there's no need to require an iterator
of Commits.
This commit also adds a `CommitIteratorExt` that makes it easy to convert an
iterator of `&Commit` to an iterator of `&CommitId`.
I keep typing `--to` since I'm used to `jj move` interface. It is
also shorter.
Currently, if I type `--to`, clap unhelpfully suggests whether I
meant `--tool`.
Like -r/--revisions, it should be okay to filter synced/non-tracking remote
branches by name.
conflicts_with_all = "tracked" is redundant, so removed as well. The tracked
field declares that it conflicts with --all-remotes.
resolve_revset_default_single() will be inlined instead. Since "default_single"
evaluation can return multiple revisions, the CLI interface usually accepts
multiple arguments. This suggests that there would be no external callers of
the singular resolve_revset_default_single().
If the --siblings option is used, the target commit is split into two sibling
commits instead of parent and child commits. Any children of the original
commit will have both siblings as their new parents.
#2274
This refactor will allow us to reuse new `rebase_descendants` function for the
`jj split --siblings` feature (#2274) and later possibly for `jj parallelize`
(#1079).
When the caller needs a formatter, it's because they're doing
something non-trivial. When the user passed `--quiet` (see upcoming
patch), we should ideally skip doing related work for print the
formatting output. It helps if the `Ui` object doesn't even return a
`Formatter` then, so the caller is forced to handle the quiet case
differently.
Thanks to Yuya for the suggestion.
evaluate_programmatic() should be allowed here. AFAIK, the contract is that
the expression should never contain any bare symbols and "fallible" symbol-like
expressions, which doesn't apply to branches() and remote_branches() functions.
evaluate_revset() is removed because there are no callers. However, it's simple
and basic function, so we might want to reintroduce it if needed.
Many callers of resolve_revset() and evaluate_revset() will be migrated to
this wrapper. "single" and "default_single" APIs won't be replaced because
they require more contexts to construct error messages.
id_prefix_context() now uses bare revset::parse() to avoid dependency cycle.
If "all:" is specified, an empty set should be allowed within that expression.
So the additional check we need here is to ensure that the resulting set is not
empty.
